I am studying mechanisms associated with the burial and sequestration of organic carbon within marine sediments and their impact on the global carbon cycle. In particular, I am interested in studying how the physical protection of organic matter is enhanced or reduced by different iron concentrations. Currently my experiments involve studying clay precipitation mediated by heterogeneous cultures of marine cyanobacteria.

Through organic geochemical and micropaleontological analysis, I study the information preserved in sedimentary archives. As part of the Bosak lab, I continue to characterize body fossils from the Neoproterozoic interglacial period to better understand early eukaryotic radiation and possible connections with the dramatic environmental change associated with the Sturtian low-latitude glaciation.

My current research focuses on microbe-mineral interactions. I employ a variety of microscopy techniques and chemical analyses to investigate the formation of minerals around microbial filaments. My goals are to explore the mechanisms of fossilization and to determine what depositional environments are most conducive to fossilization.
Currently I am investigating how bacterial gas production and consumption vary dependent on atmospheric composition, mainly focusing on photosynthesis. The goal is to have a better estimate about how life could affect the atmosphere on an exoplanet and thereby provide better markers for detecting life in the universe.

I am passionate about microbiology. I’m currently interested in understanding how sulfate-reducing bacteria respond to variable environmental conditions, such as nutrient limitation, and how those changes affect their metabolism. Ultimately, this might give us an insight into how sediments are influenced by the microbes living in them.
